Grid lines disappear when mostly needed

When using 60x60 luminaires the gridlines (drawing aids) can be very helpful.

When I add the gridline in a certain room, it looks like a good starting point to add the luminaires.

However when I try to add the rectangular Luminaire setting, the grid disappears. No way to precisely put the luminaires in the right place.

How can I avoid the disappearance of the drawn
